Apple has released the iOS 5 public version few hours back, many people has updated their device to the new iOS 5 and many of them are waiting or facing critical problems while updating to new firmware version. There are also a group of people who keep asking us about the unlock of iPhone 4 & iPhone 3GS baseband on iOS 5, as the dev team announces in the morning before the launch of iOS 5. It is possible to enjoy the unlock on iPhone 4 and iPhone 3GS while running Apple’s new iOS 5, all you have to do is wait for their jailbreak software update means PwnageTool or go with Sn0wbreeeze which allows you to preserve your baseband while updating to the next generation iOS 5.

The above mentioned unlock method is software based which was introduced by the iPhone Dev Team back in the start of iPhone, when geohot releases its first ever jailbreak for iPhone. The second unlock method to bypass Apple’s iPhone baseband is the hardware unlock solution – Gevey Unlock SIM, a sim holder with micro-chip which allows to perform unlock without performing any additional task. But both of the unlock method still stuck you can only get unlock on iOS 5, if you have supported BB and while updating to next version if you had preserved your baseband. Well at this time you can only goes with iH8Sn0w’s Sn0wbreeze because it allows to preserve your baseband and cook custom firmware for your device. After preserving baseband, you can still enjoy the unlock by kicking Gevey SIM inside your iPhone or by installing UltraSn0w, but only if you have supported baseband.

Stay away from the Redsn0w jailbreak because it only gives you tethered jailbreak and also updates your iPhone baseband to the new iOS 5 baseband which means you would lost your jailbreak chances.
